GEORGE H. TILFORD, OF PROVIDENCE, RHODE ISLAND;

PIN-TONGUE AND HINGE-JOINT FOR BREASTPINS.

SPECIFICATION forming part of Letters Patent N 0. 731,245, dated June 16, 1903. Application filed February 13, 1903. Serial No. 143,217- (No model.)

To all whom it may concern..-

Be it known that I, GEORGE H. TILFORD, a citizen of the United States, residing at Provideuce, in the county of Providence and State of Rhode Island, have invented certain new and usefullmprovements in Pin-Tongues and Hinge-Joints for Breastpins, of which the following is a specification, reference beinghad therein to the accompanying drawings.

Like letters indicate like parts.

Figure 1 is a side elevation of a breastpin provided with my improved pin-tongue and hinge-joint. Fig. 2 is a plan of the hingejoint before bending. Fig. 3 is a view showing the pin-tongue and pin-catch in side elevation, the back plate of the breastpiu in central longitudinal section, and the hinge-jointpartly in side elevation and partly in central section. In this figure the pin-tongue is shown in its open or entering position. Fig. 4is the same as Fig. 3 except that the pin-tongue is shown in its closed or Wearing position and engaged with the pin-catch. Fig. 5 is an end elevation of my improved breastpiii at the hinged end thereof. Fig. 6 is a view as seen on line a; a: of Fig. 4.. Figs. 7 and 8 are views of a modified form of my invention,"Fig. 7 showing the open position of the pin-tongue, and Fig. 8 the closed position thereof.

My invention relates to the pin-tongue of a breastpin and the hinge-joint therefor; and it consists of the novel construction and combination of the several parts, as hereinafter particularly described, and specifically set forth in the claims.

In the drawings, A represents the back plate of a breastpin, provided with the usual pin-catch B.

The hinge-joint before bending is in the shape illustrated in Fig.2, consisting of two rounded ends 0 G, connected'by and integral with a bar portion D, Each end Chas aradially-extending bent flange E and is contrally perforated, as seen at a. This joint is bent, as shown in Figs. 5 and 6, and is soldered or otherwise attached centrally to the plate A, the two ends 0 C and the adjacent portions of the bar 'D when the latter is bent v other, as illustrated in Figs. 5 and 6. Theseflanges E E when so abutted leave a certain space between the inner surfaces of the rounded portions 0 O.

The pin-tongue is designated as F. It is resilient, being made of tempered wire, and

of the flanges E-E of the hinge-joint, as seen V in Figs. 4 and 5. This curved-portion of the pin-tongue F is inserted "in the space between the inner surfaces of theparallel bentup end portions 0 C of the hinge-joint, and a pivot G passes through the holes a a of the rounded ends 0 O of the hinge-joint and in contact with the inner surface of the curve of the pin-tongue F. Thus the enlarged end of the pintongue F extends in rear of. the pivot, and the outer transverse edge of the said enlarged'or butt end re'stsand presses against the rear. edges of the flanges E E when the pin-tongue F closes to the plate A. In this manner the pin tongue F freely swings upon the pivot G and is prevented from lateral movement by its contact with the inner surfaces of the ends 0 C of the hinge-joint. The. extent of this swinging movement in an outward direction is limited by the forward edges of the flanges E E, as illustrated in Fig; 3. When the pin-tongue F is engaged at its point bin the pin-catch B, the upper edges of the bifurcated butt-end c of the pin-tongue are in forcible contact with the rear edges of the flanges E E of the hingejoint, as illustrated in Figs. 1 and 4.. In this position the rear edges of the flanges E E serve as bearing-points for theend c of -the pin-tongue and'enable the pin-tongue to be sprung into engagement with the pin-catch B.

It is obvious that instead of having the hinge-jointprovided with integral'flanges E E which are bentv and lie in abutment one with the other, as shown, these flanges may ICO be dispensed with and a stop-block may be used, which is inserted and secured between the ends C O of the hinge-joint in the same position and to serve the same purpose.

In Figs. 7 and 8 I show a modified form of my invention, in which the butt-end .of the pin-tongue (designated in said figures as c) is not thinned, spread, or bifurcated, but is simply bent angularly outward. In this construction the end a of the pin-tongue in coming in contact with the portion D of the hingejoint limits. the outward oscillation of the pin-tongue, as seen in Fig. 7, and in coming into contact with the rear edge of the flanges E E finds a bearing against the same for enabling the springing of the pin-tongue, as seen in Fig. 8.

I claim as a novel and useful invention and desire to secure by Letters Patent 1. In a breastpin having a back plate and a pin-catch, the combination therewith of a hinge-joint centrally secured thereto and comprising two parallel walls or sides which are perforated and also two flanges bent into' abutment one with the other, a pivot passing through the perforations of the walls or sides of the hinge-joint, and a resilient pin-tongue bent into a curve and inserted at its curve beneath said pivot and between the sides or walls of the hinge-joint and provided with a butt-end adapted to bear against the rear edges of said flanges of the hinge-joint when the pin-tongue is closing to the pin-catch, all arranged and operating substantially as shown and for-the purpose specified.

2. In a breastpin, the combination of a plate, a pin-catch, a hinge-joint secured to said plate and having two parallel perforated sides, a pivot mounted in the perforations of said hinge-joint, a stop located between the sides of the hinge-joint on the rear thereof near the top, a resilient pin-tongue having near its blunt end a curved bend and terminating in an enlarged end, which curved portion extends between the sides of the hingejoint and beneath said pivot with said enlarged end extending in rear of said pivot and movable into contact with the rear end of the stop when the pin-tongue closes to said plate, said stop also being so placed that the pintongue is limited in its outward movement 'by its contact with the forward edge of the stop, substantially as described.

3. The improved breastpin herein described, consisting of the combination of a plate, a pin-catch, a hinge-joint with two parallel perforated sides, a pivot mounted in the perforations of said hinge-joint, a stop caled between the sides of the hinge-joint on the rear thereof near the top, a resilient pintongue having a curved bend which extends beneath said pivot and also having a laterally-enlarged. end which extends in the rear of the pivot, the outer transverse edge of which enlarged end is adapted to rest against said stop, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
